Record-high radiation levels at Japan plant

Tokyo: Radiation levels inside a stricken reactor at Japan’s Fukushima nuclear plant have hit a record high capable of shutting down robots, in the latest challenge to efforts aimed at dismantling the disaster-hit facility.

Radiation levels inside the plant’s No. 2 reactor were estimated at 530 sieverts per hour at one spot, Tokyo Electric Power Co (Tepco) said Thursday after analysing images taken by a manually-operated camera that probed the deepest point yet within the reactor.
